Kali Picricum.

Potassium picrate. C6H2K(NO2)3O. Trituration (which must be made with great care, on account of the explosive nature of the salt).

Clinical.-Eructations. Jaundice.

Characteristics.-Allen quotes from Wolff and Gouzee the following constant pathogenetic effects observed in patients to whom K. pi. was given for intermittent fever: jaundice; diarrhoea; pain in pit of stomach; violent eructations; colic; urine clear, brownish red, not from bile pigment, but from large quantities of urate of ammonia.-K. pi. is an intensely yellow salt, and yellow substances generally act powerfully on the liver, as is the case with Picric acid itself and its other salts.
